ing wooden lining and flooring, and has particular reference to a novel side and floor construction suitable for use in box and gondola cars.

The particular object of my invention is to provide a construction of floor, and side and endlining for the above classes of cars, which will result in a car which will, without the use of an increased quantity of material, exclude' moisture, prevent the leakage of 'grain or other granular lading, and prevent the` outward bulging between the side posts of the lowermost boards of the lining, which lif permitted leaves a space between the flooring-.sand lower side boards and consequent-leakage' of the lading, and which will permit of the removal of the ioor boards for the purpose of repair or replacement, without the necessity of removing one or more of thel side lining boards which is essential in other constructions of this character with which I am familiar.

` In `the practice of my invention 1 contemplate theuse of Vametallic underframe, such as isused ,in standard practice, having the usual center and side sills, holsters, and cross bearers.4 and floor stringers of 'either wood or metal-.combined with the construction of my invention to attain the aforementioned objects.l

The 'invention will be more readily 4understood by reference to the drawings accompanying this speciication. 1n which like reference' characters'refer to like parts and in which: y A i Figure 1 is a vertical cross section. of a portion o f a car takennear to the bolster member. Fig. 2is an enlarged section ei a portion of Fig.v l, siewingmoreplearlythe construction' of my invention. eig. 3 -i's a cross section of' portion o .agcar showing a modification of my inrentiomand i is an enlarged section of a portion ofFlg. 3.

VReferring moreV particularly to the drawonlyv one half of they width -thereof being shown- 'consists of channel center sills l. channel side sills 2, bolster members 3. and the usual crossbearers and end sills. the two last mentioned notbeing `shown in the drawings. ,Side posts or stakes l, anddiagonal braces if necessary, extend upwardliv at ina` tervals and form the side framing of the car. The holsters are shown as being coniposed of web plates 5, top andbottoni stiffemng members 6 and T. and top and bottom tie platesl S and 9, and are securedto the center sills 1. and side sills 2. in the 'usual mannen The floor l0 is supported by the floor strangers 11, which may be ot' wood as shown in the drawings. or of metallic commercial. sections, and extend substantiallv from end to end of the car. i l

when wooden stringers are used the floor ingboards 10 ma;v be nailed-or bolted to the stringers l1. .or ifmetalliestringers of com merclal section are used, the flooring boards may be bolted to them by bolts passingr through holes in the stringere and flooring boards. V f i The end portions 12 of the-'flooring boards 1'0, are halved or reduced to about one half ot' their original t-hicknessgsuch reduced portions exteuding for a distance` from the ends of the boards, sufficient to' permit the reduced portions to. rest on 'the Wooden subsill 13. which rests on the side sill 2. and 4extends for the full length of the side of the a downwardly projecting portion 14; which engages the edge of the flange of the side sill 2,.and at the opposite side. an upwardly The sub-sill 13. is' of'substantially' 'Z i shape in cross section. having `at one side projecting portionV 15 which engages with a groove 16 formed in the loweredge ofthe lowermost side lining boards 17. The oor boards 10 may be secured to the sub-sill 13 by means o f boltslS as shown in Figs. 1 and 2. or by'means of nails -19 as shown -in F 3 and 4, or by a combination' of bolts and nails and the sides maybe secured to the side posts by bolts 20 in the usualma'nner.

,Figsl 3 yand 4 illustrate a modification of my invention, in which the sub-sill member 13 has its upper surface 21 beveled or sloped.

ing boards 10, are .also beveled so as toimore and the reducedend portions` 12"of the floo-reasilv insure a. closeA contact with the beveled portion of the sb-'silh 'Itwill be. readily .seen that thecontact the downward lprojection 14 of the slib-sill 1 35 Wtlthe edge'of the' flange ofthe side sill 2, and .the-engagement Yof the upward-.1'.
